Cisco UCS M6 blade and rackmount servers combine compute, network, storage access, and virtualization resources into a single converged system.
Cisco UCS integrates a low-latency, lossless 10 GbE or 25 GbE unified network fabric with x86-architecture servers.

| Cisco UCS 6536 FI | 4 (16 total after breakout) | 32 Gbps FC breakout ports | The Cisco UCS 6536 FI data sheet contains more information. For more information, see the Cisco UCS 6536 FI data sheet. |
| 32 | QSFP 100 GbE | Connect to a pair of 100 Gbps-capable Cisco Nexus 9336C-FX2 data plane switches with two, four, six, or eight uplinks. The uplinks support up to seven Cisco UCS compute domains. For the Cisco UCS 6536 FI, the total number of 100 G ports is 32 for the 100 G uplinks and server ports combined. The final four ports are for FC connectivity. |
Cisco UCS B-Series blade servers, Cisco USC X210c compute nodes, and Cisco UCS C-Series rack servers provide:
- Integrated redundancy for high availability.
- Hot-swappable components for serviceability, upgrade, or expansion.
- Fewer physical components than in a comparable system, built piece by piece.
- Reduced cabling.
- Improved energy efficiency over traditional blade server chassis.
For VMware deployments, the 3-Tier Platform can scale from three to hundreds of Cisco UCS servers. The maximum number of servers requires:
- A maximum of seven Cisco UCS domains
- Ten chassis per domain with the two-link connection option for Cisco UCS B-Series blade servers
- The underlying storage array configuration
- Consistent server models within the domain or system
- Connected storage arrays that support the configured host count.
Mixed server models are supported on a Cisco UCS 5108 chassis, but they may impact the maximum permitted quantity of servers. A mixed chassis environment of a Cisco UCS 5108 chassis and a Cisco UCS X9508 chassis in the same domain is also supported.
The following table shows the maximum number of supported Cisco UCS servers by domain and by system:
| Server model and type | Servers per domain | Servers per system | ||||

| Cisco UCS X210c M6 and M7 compute node | 88 | 160 | 112 | 616 | 1120 | 784 |
| Cisco USC X410c M7 | 44 | 80 | 56 | 308 | 560 | 392 |
| Cisco UCS C220 M6 and M7Cisco UCS C240 M6 and M7 | 44 | 88 | 32 | 308 | 616 | 224 |
The Cisco UCS 64108 FI and Cisco UCS 6536 FI are not supported with a FEX. All rackmount servers are directly connected.
The following table shows the maximum number of Cisco UCS B-Series blade servers to deploy. The limits apply when the blade servers are directly connected to Cisco UCS C-Series rack servers in the same domain.

Order CPUs from the factory or by ordering an additional server through the expansion services. By default, all Cisco UCS servers come with local M.2 cards installed for booting the operating system.
